Abstract

Summary

Global Navigation Satellite Systems (GNSS) are used in almost all fields. The achievement of this is wide availability, weather independence and high positioning accuracy, to achieve which a number of factors must be considered, the most influential of which is the tropospheric delay. It cannot be excluded completely and is difficult to model, especially its wet component. In this work the accuracy of zenith tropospheric delay (ZTD) determination by online services using precise point positioning (PPP) method is evaluated in comparison with the results of radio sounding data processing. For this, data from Praha-Libus aerological station and GOPE GNSS station are used. The mean square root errors of ZTD determination were calculated for four online PPP services.
